Power BI Reporting – New Development vs Enhancement

Pros 

Cons 

• New Architecture will directly connect to data sources if in case report consumes pre-generated reports from same source systems. 

• The new development will be done while keeping in mind that future enhancements can be made easily. 

• New expressions/logic/calculation(s) will be written in such a way that there will not be any performance issue as data increases. 

• Slicer(s) will be used instead of filters used in existing dashboard. Slicer(s) will provide smart interaction with visuals while filter(s) simply filters the data. 

• Custom visual(s) can be added per business requirement. 

• Role based Security can be added so that one group can see their own report One cannot see the data of another group. 

• Need to design same visual(s) again in most of the case(s) 

• Development efforts will be more 

• Testing efforts will be more

Pros 

Cons 

• Less development work is required 

• Less testing is required 

• Business may comfortable with the existing view of dashboard

• Data transformation section will change if new integration is happening. 

• Data Modelling section will change if new integration is happening. 

• Need to change existing aggregation(s) / Calculations if there is a performance issue.
